Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION

The invention relates to a ski, a monoski, the upper surface of which is composed of a layer of synthetic material, at least in the gliding area, the upper surface being non-planar and having a raised central portion in the shape of a shell. A snow planing plate, such as a surf plate or similar snowboard, which is on each side of said top layer at a height not exceeding the height of the plate (board) in its same cross section. It has auxiliary reinforcing edge elements that support the corresponding edges.

[0003]

[Prior art]

The snow-sliding plate defined above is the so-called "DU".
ALTEC "design (SKIS ROSSIGNOL
S. A. It is manufactured according to the registered trademark registered by the company).

The cross section made on a "DUALTEC" type ski is generally constituted by: -a lower base for gliding, with metal edges on each side, A "lower" reinforcing layer, which optionally rests on this bottom surface; a core, which may be, for example, a wooden core or a polyurethane core, preferably obtained by injection moulding, a longitudinal reinforcing element forming this core Auxiliary lateral edge elements, located on each side of the ski, no higher than the height of the ski, and the inner surface being lined by a "top" reinforcing layer over all or part of its width, A plastic covering the ski from one edge to the other, carried on each said auxiliary reinforcing edge element, either directly or on any side of the ski, Upper layer, i.e. the upper surface layer.

These auxiliary reinforcing edge elements, which are substantially perpendicular to the surface of the bottom surface, do not form part of the already generalized design of so-called "shell" skis, in which case the top layer is This is because the shell is directly carried on the lower edge of the ski. So-called "DUALTE
In the "C" design, the effect of the edge element is to increase the efficiency with which the force exerted by the skier on the upper surface of the ski on the upper surface of the ski is transferred to the lower metal edge, ie, effectively to the sliding surface, It is to improve the efficiency of skis over conventional shell skis.

[0007]

[Problems to be Solved by the Invention]

The present invention provides for snow (or other snowboards) manufactured according to the "DUALTEC" design described above, by optimizing the connection of the ski shoe bindings to the skis or other snowboards to provide snow coverage. The objective is to improve the transmission of the skier's propulsion.

In fact, in order to obtain good efficiency, it is very important that the forces generated by the ski boot are transmitted as directly as possible to the lower flanks of the ski.

It is known to provide within the gliding area a plate or platform for lifting shoe bindings and receiving these bindings, which plate or platform is at a distance from the upper surface of the ski. Can be positioned.

It has been found that such a binding lift plate or platform is presently needed because the width of the downhill ski is reduced in the run area, part 1.
One consequence is that the shoe sticks out to the sides and then to the snow whenever the edge contact is high, which can lead to skidding on the ski in tight bends. When fully lifted, there is almost no risk of the shoe rubbing when the ski leans to the side considerably, so that the ski can be used normally, especially in slalom.

Here, the "sliding area" means an intermediate area which is located between the front part and the rear part of the snow slide plate, on which the shoe binding is mounted.

[0013]

[Means for Solving the Problems]

Accordingly, the invention provides a ski having a raised central portion, at least in the gliding area, the upper surface of which is composed of a layer of synthetic material, the upper surface layer being non-flat and shell-shaped in cross section. Related to snow planing plates, such as plates, monoskis, surf plates or similar snowboards,
This snow-sliding plate has, within the same cross-section, a longitudinal reinforcing element of a height not exceeding the height of the plate, and having auxiliary side-reinforcing edge elements provided at least in the sliding area, The layers are carried on either side of the plate by its two side parts, directly or not, on each of said auxiliary reinforcing edge elements, the snow-sliding plate receiving shoe fasteners. And at least one rigid platform for lifting, the rigid platform having an inverted U-shaped cross-section, whether directly by its foot or not, of the lateral reinforcing edge element. A recess that is positioned and dimensioned to receive the foot on each side of the top layer of the board on each side and at each foot site of the platform. Have,
The length of each of these indentations is approximately equal to the length of the matching feet of the platform, and the width is greater than or equal to the width of the base of this foot that rests entirely on the indentation :.

The rigid platform preferably has at least two legs.

According to an advantageous embodiment, the reinforcing edge elements are each positioned in the gliding area and are significantly wider than the rest of the edge element over at least a limited length, including the depressions. Has at least one part that is wide.

The reinforced edge element may be located in the gliding area, the latter including the foot of the platform or extending over the entire carrying length of the board.

The "carrying length" of a snowboard is intended to mean the length of its surface which contacts the ground when the user stands upright on it.

【Example】

The invention can be understood more clearly by reading the following description with reference to the accompanying drawings.

FIG. 1 is a general perspective view of a downhill ski according to the invention, with a platform for lifting the binding, with the binding shown in a developed state.

2 and 3 are cross-sectional views taken along lines II-II and III-III of FIG. 1, respectively.

FIG. 4 is a sectional view taken along line IV-IV in FIG.

FIG. 5 is a view similar to FIG. 3, but with the platform in place on the ski.

FIGS. 6, 7 and 8 are similar to FIG. 5 and show the first three variants.

FIG. 9 is a side view of a downhill ski according to the invention in another variant embodiment.

10 and 11 are respectively XX and X of FIG.
It is a transverse cross-sectional view along I-XI.

FIG. 12 is a view similar to FIG. 9 and shows the final variant embodiment.

Referring now to the drawings, first FIGS.
Is a so-called "DUALTEC" type on-piste ski 1, with on each side of the ski a lateral reinforcing edge element 2, 3 which, in the gliding area, rests on each lower edge 4, 5. Alternatively, an "alpine ski" is shown.

This ski is perfectly symmetrical with respect to the central longitudinal plane 6 and appears in the same cross section, constituted by: with metal edges 4, 5 on each side. A lower bottom surface 7 for sliding; a lower reinforcing layer 8 resting on this bottom surface 7; a polyurethane core 9 obtained by injection molding a compound of polyurethane foam; Contacting: two auxiliary side edge elements 2, 3 which form a longitudinal reinforcing element and do not exceed the height of the ski and rest on the corresponding edges 4 and 5, a layer of synthetic material A top coating which, in the gliding area, forms a shell body 10 whose inner surface is lined by an upper reinforcement layer 11, which shell body on either side is provided by two side flanges X and Y of the ski. 2 in the central area The reinforcing members 2 and on the 3, and is supported between the front and rear edges 4 of the ski on the 5.

According to the invention, the ski 1 is equipped to receive in its sliding area a rigid platform 12 for receiving and lifting the ski boot bindings 13A, 13B.

This platform 12 is integrally molded and therefore consists of only one top plate. Its cross section is U-shaped upside down, with 4 legs 1 as a whole.
Similar to a low table with four, each of these feet has four connected female depressions 1 in the shell of the ski 1.
Mounted in 5, and in these recesses or notches 15 rest firmly on the corresponding bearing surfaces 20 and 30 of the reinforcing edge element, so that the latter is widened over the entire length of this recess. The width L1 of the bearing surfaces 20, 30 of the reinforced edge elements 2, 3 as shown in FIGS. 3 and 5 runs over the length L2 of these recesses 15 and thereby overlies the corresponding side reinforced edge element 2 or 3. Corresponding shell 10 (backed by reinforcement 11)
Has a value larger than the width L0 of the substantially flat and horizontal edge of. Each of these depressions 15 is thus of length L2, approximately equal to the length of the connecting foot 14 of the platform, and the width L0 is such that the base of this foot 14 lies flat over substantially the entire depression 15 At least equal to the width of.

The single platform 12 preferably has at least three feet 14 and is more flexible and lighter than a conventional platform incorporating continuous side flanges, thereby allowing it to fit on the flange of the shell. It therefore rests on the corresponding edge elements 2 and 3. Due to its shape, this integrated platform 12 makes it possible to separate the ski from the tightening part of the shoe by ensuring a certain distance between the front stop and the rear heel of the tightening device.

According to FIG. 5, a rigid platform 1
2 is the screw 1 after the positioning work in the four recesses 15.
It is fixed to the edge elements 2, 3 by 6. In this case, it only rests on these edge elements 2, 3 by the foot 14 (in this case sandwiching two layers of material constituted by the shell 10 and its reinforcement 11), which is 14 is high enough to create a free space 17 between the upper surface 18 of the ski and the lower surface of this platform 12. The forces exerted by the skier in this case act directly via the platform 12, its foot 14 and the edge elements 2, 3 on the edges 4, 5 which are the main object of the invention.

The thickness and shape of the platform 12 is such that the screw 31 for holding the fasteners 13A and 13B has the shell 10
Selected not to penetrate.

In general, the length L2 of each of the four recesses 15 preferably has a value of the order of 3 centimeters,
Obviously the same is true for the corresponding dimensions of each foot 14.

The longitudinal distance D between the two pairs of opposite indentations corresponds to the space located in the gliding zone, which is preferably of the order of 40 centimeters.

Of course, the invention is not limited to the embodiments described above, but many variants are conceivable.

For example, the platform 12 can itself be the base, conventionally made in the form of a slip surface, for shoelaces, so that the platform and the slip surface are front stop and / or Or accept the body of the heel.

In fact, conventional fasteners are generally known to include a base forming a smooth surface, and thus are known to have a "closed U-shaped" cross section, which base is the fastener body (front face). The stop and / or the rear part) allow sliding longitudinally forward or backward to adjust the binding, depending in particular on the size of the skier's shoe. According to this feature, which is specific to the invention, this lifted platform 12 therefore also serves as a slope.

Thus, the presence of the widening bearing surface of the reinforced edge elements 2, 3 is not essential, and in a simplified embodiment of the invention the width of the foot 14 of the platform 12 (at the base) is reinforced edge element. It can be smaller than the width L1 of a few, or preferably approximately equal.

In FIGS. 6 and 8, the reinforced portions 20, 30 of the edge elements 2, 3 are integrated (20 + 3) over the entire width of the ski 1 at the respective recesses 15.
0) It can be extended to that location.

According to FIGS. 7 and 8, at the location of the depression 15,
Alternatively, viscoelastic anti-vibration layers 27, 28 may be provided, preferably below each foot 14 of the platform, and above each respective reinforced edge element 20, 30 (sandwiching layers 10 and 11 as shown). You can also).

Instead of resting on the edge elements 2 and 3 via the layers 10 (shells) and 11 (upper reinforcement), whether or not they involve the widened portions 20 and 30, the feet 14 of the platform 12 Can be placed directly on these edge elements 2 and 3 and the layers 10 and 11 at this point can be eliminated or placed on these edge elements via either 10 or 11 of these two layers And in the latter case, the other layer 11 or 10 is eliminated from that location, whereby the viscoelasticity between each foot 14 and the edge element 2 or 3 on which it rests directly or indirectly. It does not prevent sandwiching the layers at all.

In a modified embodiment of the invention, the space 17 created between the upper surface 18 of the ski and the platform 12 can be filled with a layer of viscoelastic material instead of a simple layer of air.

This platform 12 can have six or more feet 14 instead of four, the same number of recesses 15 being provided in the ski 1.

According to another variant, the platform 12
Can be asymmetrical with respect to its longitudinal axis, ie with respect to the central longitudinal plane 6 of the ski, and the same can be provided in a combined manner with the possible widening 20 of the edge elements 2, 3. It can also be applied to 30 and its associated recess 15 in the shell 10.

[0048] In particular, the platform 12 allows the skier to have two skis on the inner edge side of the ski, or more generally two skis, than the other side (or the outer side), in order to further maintain the ski's bending stability. A smaller number of feet 14 can be provided on the inside of the ski when worn on its feet. For example, the platform 12 may comprise only three feet 14, ie one foot on the inside (inner edge) of the ski and two feet on the outside (outer edge) of the ski. it can.

The ski in question is not necessarily a ski with metal edges. This is also true for skis that do not have edges on the lower flanks, as do most cross-country skis today.

The platform 12 is here a metal platform, for example of aluminum alloy. Also composite materials (epoxy glass fiber, reinforced polyurethane,
Etc.).

Instead of being integrated, fasteners 13A, 1
The platform 12 that receives 3B can also consist of two parts, namely a front part 13A of the fastener or a front part for receiving a "stop" and a rear part 1 of the fastener.
3B, or a rear part that accepts "heels". In such a case, the front portion of platform 12 is preferably
The rear part of this platform 12 is prepared to be fixed in the edge elements 2, 3 of the ski, for example by fixing screws 16 etc. according to FIG.
Underneath its respective foot 14, there is a bottom 27, 28 made of viscoelastic material, these viscoelastic layers 27, 28 being
On the one hand glued under their respective feet 14,
On the other hand, they are respectively glued onto the two receiving flanges X, Y of the shell 10 on which they rest. This measure makes it possible to prevent the ski from hardening more efficiently.

Another embodiment according to the invention, which is also very efficient in preventing hardening of skis, is shown in FIGS.
1 is shown.

According to this embodiment, the one-piece platform 12 has feet 14 only on the front side of this platform and, like all the platforms 12 mentioned above, thereby rests on the reinforced edge elements 2, 3. ing.

On the other hand, it has no rear foot, preferably extends over the entire width of the upper surface 18, and via at least one viscoelastic wedge 32 adhered both on this surface 18 and below the platform 12. It rests on the upper surface 18 of the ski.

Finally, FIG. 12 shows the final embodiment, which is an integrated platform 12
Differs from that of FIGS. 1 to 8 in that it only has a foot 14 in its central longitudinal portion 12M (eg, the illustrated non-limiting example includes two feet, but four feet). Can also be provided) so that its front portion 12A and rear portion 12B both overhang with respect to this central portion 12M and are positioned a short distance "e" above the upper surface 18 of the ski. ing.
